Beyond the color needing to be black...what years do the different shapes (where they clamp down on the valve cover) correspond to? As shown in the pics, there's a pointy and flat version. And most importantly (to me), what's correct for a 1963 s90 coupe? Thx

For what its worth, my numbers matching 63 super 90 has the flat version that fit in a depressed groove in the vented covers. I suppose they could have been switched at some time during engine work. Daryl Sunny SoCal

I'm sure your flat bails are original Daryl. The flat ones are what you need Mario. Stoddard sells the flat version as NLA.04.240.https://www.stoddard.com/53904240-nla.html.html
At some point (prior to '63) they must've changed the design and kept the part number - and didn't change the picture in the parts books. I had all my parts manuals open yesterday researching another project - thus my earlier reply. My pre-A and A engines ('58 and older) all have the pointy version bails.

As a reference:-
Herewith a photo of my `65 C's valve cover and bail.
Note the contact widths of the bail and the cover's steps. I believe they are the same as on your car.
